What is AIFC?
AIFC stands for Compressed Audio Interchange File. Compressed .AIFF audio file
that contains CD-quality audio; similar to a .WAV file, but uses audio compression
to reduce file size; may incorporate ULAW, ALAW, or G722 compression; commonly
referred to as an AIFF-C file.

AIFF-C is being defined because AIFF does not allow for compressed audio data.
AIFF-C adds the ability to store compressed audio data in a standard manner. Naturally,
AIFF-C also allows the storage of uncompressed audio data. The "C" in
AIFF-C signifies its extension to handle compressed audio data.

The differences between the original AIFF and AIFF-C were kept to a minimum.
Applications which currently support AIFF should be easily upgradable to AIFF-C.

The following changes have been made from AIFF:

The FORM identifier was changed from 'AIFF' to 'AIFC'. This distinguishes
AIFF-C files from AIFF files. Existing AIFF programs, until they are upgraded,
will simply ignore AIFF-C files.

The Common Chunk has been extended to include a compression type ID and a
compression type name. AIFF-C is thus capable of storing compressed audio data
generated from any compression algorithms.

The Sound Data Chunk can contain compressed audio data. The Chunk format has
not been modified.

The Sound Accelerator (Saxel) Chunk is new. It is designed to eliminate initial
artifacts caused by the de-compression algorithms when playback begins at a random
point defined by a Marker.

The Format Version Chunk is new. This Chunk is designed to provide a smooth
transition for potential future upgrades to the AIFF-C specification.

What is AMR?
Adaptive Multi-Rate (AMR) is an audio data compression scheme optimized for speech
coding. AMR was adopted as the standard speech codec by 3GPP in October 1998 and
is now widely used in GSM and UMTS. It uses link adaptation to select from one
of eight different bit rates based on link conditions.AMR is also a file format
for storing spoken audio using the AMR codec. Many modern mobile telephone handsets
will allow you to store short recordings in the AMR format.
